One of possible cardiac failure therapy is mechanical heart supporting. The following types of ventricular assist devices (VAD) are clinically used: diaphragm displacement, centrifugal and axial pumps. Each of supporting devices produces different hemodynamical effect and affects the circulatory system in various ways. It causes impossibility of therapeutic effect comparison obtained by different pumps' treatment. A lack of defined physical parameters describing phenomena inside the pump and its influence on circulatory system are an obstacle during new supporting devices designing. The goal of investigations is to create a set of physical parameters which characterized pump's operating and its cooperation with circulatory system.
